High Gain Bulk-Driven Operational Amplifiers for SOC Applications
Organization: Indiana Univ-Purdue University Indianapolis
This invention relates to a SOC (system on chip) design for an operational amplifier, which provides the highest open loop gain of any bulk-driven amplifiers. The design would be of value to any low power, voltage analog and mixed-signal CMOS integrated circuit design, which operate at low voltage and low power, such as hearing aids, implantable cardiac pacemakers, cell phones and other portable hand held devices. Operational amplifiers are required in a wide range of signal processing devices, including analog-to-digital converters, analog ...
Frequency Modulated Analog to Digital Converter
Organization: Indiana Univ-Purdue University Indianapolis
This analog to digital converter (ADC) circuit uses a frequency modulation (FM) approach to obtain a device which uses less than 10% of the power of conventional designs and will scale well in future low voltage circuits in 0.18 mm CMOS and below. Current wired and wireless telecommunication devices typically demodulate an analog FM signal and then convert it to a digital signal for digital signal processing. With this concept, analog mixers, demodulators and down-conversion mixers are eliminated, reducing the power requirement and ...
Method and Apparatus to Reduce Noise Fluctuations in On-Chip Power Distribution Networks
Organization: Indiana Univ-Purdue University Indianapolis
The invention offers a circuit design technique for reducing the noise fluctuations in on-chip power distribution networks. This noise often results when digital circuits are switched, producing current peaks which cause voltage fluctuations in power supply lines due to the inductive behavior of on-chip or chip-to-package interconnects. Previous attempts to reduce this noise which is becoming increasing a limiting factor in high speed, very deep submicrometer circuit designs, have focused on ground bounce, by lowering the inductance in the ...
Low Swing Dual Threshold Voltage Domino Logic Circuits
Organization: Indiana Univ-Purdue University Indianapolis
The invention offers a domino logic circuit for microprocessors with lower power consumption than current designs without sacrificing noise immunity. It employs sleep switch transistors and a dual threshold voltage transistor distribution for placing a domino logic circuit into a low leakage state. Current aggressive circuit design which focus solely on enhancing circuit speed in microprocessors, consume power levels that impose a limiting factor on system performance and functionality. Attempts to reduce power consumption by lowering the ...
Digital CMOS Voltage Interface Circuits
Organization: Indiana Univ-Purdue University Indianapolis
This invention relates to digital CMOS voltage interface circuits, particularly, voltage interfaces which transfer the digital signal between any two voltages, with minimal power dissipation. CMOS is the principal technology used today to implement high performance digital as well as analog applications. When scaling a CMOS technology, the supply voltages are decreased to control electric field inside transistors and also to reduce dynamic power dissipation. This however reduces circuit speed. To overcome this drawback different power ...
